The fire was at 145 acres and was not natural, according to fire officials. Investigators believe it was human caused but they have not pinned down the exact cause at this time, forest officials said Sunday afternoon.

The Fisher Fire is located on Fisher Canyon area approximately six miles from Flagstaff, according to the U.S. Forest Service.

There are six hotshot crews, two bulldozers, two helicopters and six engines all being used to fight the blaze.

There is an area called Heckethorn southwest of the fire and the closest subdivision to the blaze. There are also some Indian ruins in the area of the fire.

Fire crews said the prevalent southwest winds are pushing the fire away from those structures. Large gusts on Sunday were expected but firefighters say it did not become problematic to containing the wild fire.

The blaze is burning in timber on slopes and spreading to the southeast, away from Flagstaff.

Several crews were rerouted from the fire on Sunday to fight another fire that sparked just southwest of Lower Lake Mary at a campsite. Officials said that fire was quickly contained to about a quarter acre.
